Title: Flow measuring equipment
Inventor: WADA ICHIRO
IPC: G01F1/66
Filed: 1989-06-08
Abstract: PURPOSE:To measure flow rate accurately by a method wherein attachment in a measuring tube is removed by fluid increased in flow speed due to decrease in a cross-sectional area of the measuring tube when a balloon is expanded. CONSTITUTION:When attachment on an inner surface of a measuring tube 201a of a flow meter 201 is to be removed, a motor is rotated to have a power reel 205 and a power roller 207 operated toward a feed-out direction with fluid to be measured being flowed. A balloon 208 is gradually expanded into a flow path and flows into the measuring tube 201a due to flow of the fluid. At this time, the balloon 208 is expanded by feeding air from a feeding and exhausting device 206a via a feeding and exhausting pipe 206. With the balloon 208 expanded, a substantial cross-sectional area of the measuring tube 201a is reduced, thereby accelerating fluid flowing along the inner surface of the measuring tube 201a. This accelerated fluid causes attachment on the tube wall of the measuring tube 201a to be peeled off and removed. Therefore, the flow rate of fluid to be measured can be accurately be measured.

Filed: 1979-11-13
Abstract: PURPOSE:To obtain accurate position information of ghost by providing a control pulse memory circuit and by using signals which have a constant time relation, generated from the circuit. CONSTITUTION:When a ghost is detected by using a transversal filter, it is necessary to detect how far the ghost signal is from a synchronizing signal part and then store it as position information by a digital signal. Then, if the synchronizing signal itself is disordered when the distance between the synchronizing signal and the position of the ghost is measured, the position information of ghost becomes inaccurate. For this purpose, control pulse memory circuit 28 is provided and signals, havng a constant time relation, obtained from this circuit 28 and the vertical synchronizing pulses are used to obtain accurate position information of ghost.

If a dye having the position bicolor property and a nematic liquid crystal having the positive dielectric anisotropy are used as these bicolor dye and nematic liquid crystal respectively, what is called negative display is obtained. That is, liquid crystal cells are colored in the turn-off state because the bicolor dye absorbs the light sufficiently, and the transmittance in the turn-on state is higher than that in the turn-off state because light absorption of the bicolor dye is reduced in the turn-on state.

Abstract: PURPOSE: To provide the title copper alloy whose wear resistance, heat resistance and workability can be enhanced by limiting the contents of tin and Cr.  
     CONSTITUTION: A copper alloy for trolley wires is refined consisting of, by wt., tin; 0.1W0.4%, Cr; 0.03W0.2% and the balance copper essentially. For example, usual copper metal is melted at 1250°C and deoxidized. After adding tin as its element and Cr as a Cu-15%Cr mother alloy to the molten copper, they are dissolved well with stirring and continuous-cast into a 120 mm square ingot. The ingot is hot rolled at 850°C and cooled with water. The resulting rough wire of 22.5 mmϕ is then worked into a grooved trolley wire of 110 mm 2  by surface cutting and cold drawing. Thus, the trolley wire with superior heat resistance and superior sliding wear resistance at the time of current collection can be obtd. without deteriorating the castability and cold workability, and requiring troublesome heat treatment.
